well ther Typhoon could take off on a helipad...so we could say a lot of places could have it...however i know the accomodation was condemned at Lyneham..so would doubt it being there.
I'm guessing at Leeming...it has all the facilities....hangers, accomodation is fairly new etc and also talk of the Arrows moving to Leeming if and when they sell Scampton
